Today, the park’s amphitheater is named after the legendary musician/counter-culture guru who died in 1995. Sunday would have marked his 68th birthday.

Jerry Day — put on by the Excelsior Cultural Group and the San Francisco Parks Trust — celebrates Garcia and the neighborhood. In addition to live bands, there’ll be food and arts and crafts for sale. Admission is free, but organizers welcome donations to help pay for the only-in-San Francisco event.

Music starts at noon, with the last act, Melvin Seals and the Jerry Garcia Band, scheduled to take the stage at 3:30 p.m. The amphitheater is located off of 45 John F. Shelley Drive. More information can be found at www.jerryday.org.
